To do so: - imply (enable) OF_UPSTREAM option for E850-96 target - point DEFAULT_DEVICE_TREE in E850-96 config to upstream dts - remove now not needed local dts files, binding docs and headers - update MAINTAINERS and board/samsung/e850-96/MAINTAINERS correspondingly Upstream device tree files for Exynos850 SoC and E850-96 board are pretty much the same as local (removed) ones, so the conversion is rather straightforward and painless in this case. The appended dts file (arch/arm/dts/exynos850-e850-96-u-boot.dtsi) stays unchanged. The only remaining local dt-bindings doc for E850-96 board is exynos-pmu.yaml. It wasn't removed as it's quite different from Linux kernel version. Particularly U-Boot local version of exynos-pmu.yaml describes "samsung,uart-debug-1" property, which is not present in Linux kernel binding. Later it might be upstreamed to Linux kernel, and once it's done the U-Boot exynos-pmu.yaml binding can be removed. No functional change.

Use upstream device tree files and bindings. To do so:
 - imply (enable) OF_UPSTREAM option for E850-96 target
 - point DEFAULT_DEVICE_TREE in E850-96 config to upstream dts
 - remove now not needed local dts files, binding docs and headers
 - update MAINTAINERS and board/samsung/e850-96/MAINTAINERS
   correspondingly

Upstream device tree files for Exynos850 SoC and E850-96 board are
pretty much the same as local (removed) ones, so the conversion is
rather straightforward and painless in this case. The appended dts file
(arch/arm/dts/exynos850-e850-96-u-boot.dtsi) stays unchanged.

The only remaining local dt-bindings doc for E850-96 board is
exynos-pmu.yaml. It wasn't removed as it's quite different from Linux
kernel version. Particularly U-Boot local version of exynos-pmu.yaml
describes "samsung,uart-debug-1" property, which is not present in Linux
kernel binding. Later it might be upstreamed to Linux kernel, and once
it's done the U-Boot exynos-pmu.yaml binding can be removed.

No functional change.

serial: msm: calculate bit clock divider 2024-04-23T11:29:16+00:00 Caleb Connolly caleb.connolly@linaro.org 2024-04-15T15:03:40+00:00 69e9b3428bfee99ef3a5ece6e6c69a1ad1b39bd9 The driver currently requires the bit clock divider be hardcoded in devicetree (or use the hardcoded default from apq8016). The bit clock divider is used to derive the baud rate from the core clock: baudrate = clk_rate / csr_div clk_rate is the actual programmed core clock rate which is returned by clk_set_rate(), and this UART driver only supports a baudrate of 115200.
